One of the big issues I had with this conversion is that there are very few examples of entire front yard conversions. Most xeric designs involve turf with bordering xeric flowerbeds. Very few are a large standard suburban lot with no grass. And most of those are in Arizona and look a bit spare. So this plan is very much an experiment.
At this point we are still very open to conversion ideas. Feel free to attach any photos or ideas you find inspiring in the comments.
